The Phillies of the time played far under .500 so Hubbell did well if he broke .500. In 1920, when he went 9-9 for the team, the team was 62-91. In 1924, when he went 10-9, the team went 55-96.

Bill played in the majors before the more famous Carl Hubbell came up. However, Carl pitched in the minors beginning in 1923, and Bill went back to the minors after his major league days. They were both in the American Association in 1927 (Carl for only two games while Bill went 9-9). Bill pitched through 1932 in the minors, winning 14 with Minneapolis in 1926 and 13 with Sacramento in 1931.
